The Level 1 feeds includes everything listed in the Fundamental Message http://www.iqfeed.net/dev/api/docs//Level1FundamentalMessage.cfm

I'm not sure what you mean by "report dates in the future." The daily EDS and FSD report are compiled at about 5:30 pm each day. So the reports for 20220328 will be ready about 3 hours from now. Past reports are available going back to about April 2018, because that's when the reports were added to IQFeed.
